What are the characteristics or true Araucanas in terms of behavior and temperament? Are they calm or Flighty, relatively quiet or talkative, and are they robust and healthy or fragile? One last question is how do they do they mix with other types of hens,specificly do they get along with other types of hens and do the Roos readily service the other hens? I love the look and beautiful eggs but want as much info as possible before considering a small group of this interesting breed of chicken.
